When we print on Black Nylon Pack Cloth (rough Textured material) we add the Nylo-Bond to the plastisol and then a small amount of Puff to the ink. Amazing it covers with one pull.. Also try it on any dark material works great.. I have a lot of small prints on the nylon that require no shrinkage of the material so I use a heat gun to set the ink and watch the puff to get just the right coverage..
